The admin has whitelisted the IP's that Qlik recommends. We also added DNS for "cx273z46ee090t6.us.qlikcloud.com" per Qlik prerequisites.
Did an nslookup and also whitelisted the IP's below which are Qlik US servers.
Using windows authentication which works fine when I access SQL Management Studio.
Is there something else that needs to be configured that is not in the video?
